Command line in principle

The -i option specifies the filename of the source video. If the video file contains no audio stream, it can be read from a separate file using the -p option. The output file name is given with the -o option.

The -x option sets the video[,audio] import modules. If omitted, transcode will probe for appropriate import modules. The same aplies for the -y option, but for export modules and if omitted, transcode will encode to the null module.
